Ronian's latest paper has been published in the European Journal of Physics! In this new work, Ronian extends conventional optical radiometry to the case of non-stigmatic, non-aplanatic, and non-isoplanatic lenses. Click HERE to read the open-access author-accepted preprint!
Ronian will be giving an invited talk at the 2021 Frontiers in Optics and Photonics Symposium organized by the Indian Institute of Technology Delhi! Click HERE to download the slides!
Wrapping up the year in 2020, Ronian publishes a technical note describing how to apply a simple formula to compute the relative illumination of an un-vignetted imaging lens system in terms of image distortion, differential distortion, chief ray angle (in object space), and the size and shape of the entrance pupil.
Ronian presents a novel optical design concept for a variable focus system without moving parts at the OSA Imaging & Applied Optics Congress 2020 (online). Click HERE to see the open-access draft slides. Click HERE to link to the proceedings paper.
